If you jump...

If you're tall enough one can kind of step over their legs, it's not optimal. Considering you're flying via CMB it's shorter flights though so perhaps less of an issue

Hmm.. While it's indeed unlikely to be an issue for my SIN-DXB (via CMB) flight, it's probably more of a concern for the DXB-GVA leg. My only consolation is that I get the A380 flight on my way back (DXB-SIN). Suddenly the 1-2-1 seating feels so precious :)

The A380 is basically like EY, 2-4-2 or rather 1-2-1 staggered overlap, so all aisle access.

It's really not that bad in the 77W, the service is better due to smaller cabin. Also to GVA you'll get the new J, though still 2-3-2.

Are you referring to the 1-2-1 rows where the middle seats are right next to each other and hence can be combined ? :)

Anyway.. if I may ask about the chauffeur drive service.. My colleague will be travelling to the same destination as mine, with a different airline but arriving almost at the same time. Do you think the CD service will allow me to bring him along in my CD car? (so 1 additional pax aside from myself).

M3red is referring to F (Not Sure if you got that or were deliberately making a joke.

Regarding CD: yes

Sorry, one more question on CD. I just found out that Geneva Motorshow will be happening on the day of my arrival in GVA, and the venue is just next to GVA Airport. In that case, I'm now thinking of doing this : upon landing in GVA, retrieve my luggage, store it in the airport baggage locker. Then walk to Geneva Motorshow, and come back a few hours later to airport, to retrieve my luggage, and take the CD car.
The question is : will the CD service care whether I take the car immediately upon landing, or a few hours later ? The CD booking in Emirates website doesn't seem to allow specifying a particular departure time (it only shows my landing time).

Hm, okay... or maybe I can don't book the CD online first, and upon landing at GVA, walk over to the counter and tell them, I'm going to take their CD car in about 3 or 4 hours later. They won't do it ? :)

Do you not think that the drivers might have other trips scheduled? The CD company has a specific time window for EK trips, they do other business and will schedule drivers for that. Calling them directly perhaps they'd be willing if the margin for them is good enough

Alright.. Seems I will have to forego the CD in GVA then, for the sake of visiting GIMS. Fair trade off.

Just wondering if there is a way to check upgrade availabilty on Economy Flex to business using miles before booking?

Yes, check for business saver award in the EK Website, alternatively use ExpertFlyer but they're having issues with EK Upgrade availability right now so not sure if it's fixed yet.
